"Error creating port map" - system requires reboot every day or so

[Martinspire 1]

Hi all, merry christmas.

For a few weeks I've been having issues with Emby from external sources. I had hoped it would fix itself but apparently something is broken on my network in combination with Emby.

About every day or so I need to reboot Emby in order to access it from outside my LAN, I've tried reinstalling, I've tried assigning a different IP on the network. I've tried changing the Emby server ports and I've looked at settings I might've set that break it but I'm not sure whats happening.

What I do see is an error popping up every now and then:

Now the actively denying connection thing seems odd. I can't really find anything usefull with the 10061 error code and same goes for the Error Creating Port Map error. I've enabled UPNP on my LAN, have total control over its settings where the Emby server has a fixed IP (by the Asus router). There's no duplicate NAT or anything (my Xbox or Playstation work fine in that regard) and I can't see any other device using the IP or whatever. I've switched ports a couple of times to see if that would fix it but right now its still giving me the same error.

So is there anything else I can do to debug or even fix this?

Hello Martinspire,

Please wait for someone from staff support or our members to reply to you.

It's recommended to provide more info, as it explain in this thread:

Thank you.

Hi, UPnP using PortMapper tends to be troublesome at times. I would recommend removing the PortMapper plugin from Emby, and setup port forwarding in your router instead.

Follow this guide from the 'Setup Port Forwarding' section: https://support.emby.media/support/solutions/articles/44002137137-remote-setup

Let us know where you get stuck.

Hi, can you please attach the complete emby server log file? Thanks.

Here are some logs

 

I've tried connecting with my phone in the past 5 minutes and it just gives me no connection at all. So perhaps there's something there but I only see port mapper error. And on my local network itself it works fine. Externally (like with my phone) its not working.

Allright, gonna try this but its a shame things don't seem to work automatically anymore. Not sure whats blocking what. On my Asus Router there doesn't seem anything wrong and on my device I have BitDefender and Adguard running, but they don't seem to be in the way of connecting to emby (plus I've whitelisted everything I could think of)

Allright so set up port forwarding. I'm gonna reboot everything again but I don't see it working yet. I've got some screenshots to show the setup.

However externally doesn't seem to want to connect to the new situation

 

Also on canyouseeme.org it doesn't show as working:

Error: I could not see your service on 85.144.37.150 on port (8099)
Reason: Connection timed out

 

Edit:

Not sure what to do now. Both Port Forwarding or Triggering doesn't seem to work at all. Even switching ports again doesn't seem to fix it. Port mapper might not be a permanent solution, but at least that seemed to work some of the time.

Edit2: 

Meddling with some ports and enabled port mapping again has at least brought functionality back but I doubt it will stay online as it did before. Not sure why manual port mapping in the router didn't work but I tried a few things and made sure everything was enabled and set. But just couldn't get it to work externally. Which is weird

Because you've mapped your ports wrong, according your screenshots: it should be http External 8099 -> Internal 8098.

You don't need https as you don't have SSL set-up on your server.

Thanks for spotting the mistake. It works now with manual port forwarding. I just hope that eventually the bug gets fixed so I can turn it automatically again.
